ESP32-based WIFI progressive sleep alarm clock system

Hardware Design: Based on the high-performance ESP32 microcontroller, design and build a complete hardware system. This system will include an OLED display for clearly showing time, date, and weather information; a soft-light LED array to simulate sunrise light and help users gradually wake up; an audio decoder and speaker to play soft music to assist in waking the user; buttons for function switching, time adjustment, etc.; and a battery to ensure the system's portability and independence.


Software Design: Develop embedded software using VS Code and the Arduino environment to implement functions such as time synchronization, weather acquisition, and gradual wake-up. The software will adopt a modular design to improve maintainability and scalability. A user interface and interactive functions will also be developed to allow users to easily personalize and adjust settings. Currently, all functions work perfectly. However, when soldering, remember to reverse the Source and Ground wires of the two MOSFETs controlling the LEDs; otherwise, the LEDs will remain constantly lit and uncontrolled by the microcontroller. The image
above shows the LED before the wires are reversed, meaning the LEDs are constantly lit and uncontrolled by the program. The image below shows the LED after the wires are reversed, meaning
the LEDs can be controlled by the microcontroller for switching on/off and brightness, and other functions also work perfectly.
